Specification of Letters Patent.

Patented July 17, 1906.

Application filed January 16,1906. Serial No. 296,241.

T0 all whom it 1v1/my concern,.-

Be it known that I, JOHN M. ORTLIEB, a subject of the German Emperor, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dies for Harness- Loops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanyin drawings, and to figures of reference marker? thereon, which form a part of this specification.

The objects of this invention are to facilitate the work of making boxes or loops to receive the leather straps of harness, to reduce the cost of construction and secure a more perfect nish in the article by avoiding the impressions of seams or joints in the dies, and to secure other advantages and results, some of which may be hereinafter referred to in connection with the description of the working parts.

The invention consists in the improved die or press and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the claim.

Referring to the accompanying drawings, in which like characters of reference indicate corresponding parts in each of the several figures, Figure 1 is a plan of my improved die, showing a piece of leather therein. Fig. 2is a sectional view of the same, taken at the edge of Fig. 1. Fig. 3 is a detail perspective view showing the sections of the inner die members detached from one another. Fig. 4 is a view of the leather loop after having been subjected to the dies, and Fig. 5 is an end view of the same.

In said drawings, 6 indicates the female member of the die, comprising a comparatively heavy piece of metal having an open aperture at its upper side, the opposite side Iwalls and bottom of which are ornamented or engraved to give the desired ornamentation or engraving to the exposed surface of the leather 7. The aperture 8 extends transversely of the body or block 6, opening not only at the top, but also at the opposite ends thereof, Within said female member are arranged the male members 9 10 11 12, the wide member 9 of which is of plano-convex shape, the opposite edges being disposed near the opposite corners formed in the aperture 8 and the plane side of which lies upward and receives the wedge members 10 11 12. Said wedge members comprise the opposite side members 10 11, having perpendicular walls to engage the leather and press the same oppositely against the side walls 13 of the female die member and have inclined inner walls 14. to receive the central wedge 12, the latter having oppositely-inclined walls 141.

By inserting the members 9 10 11 12 within the doubled leather piece 7, as indicated in Fig. 2, and arranging the central wedge l2 between the members 10 11 and the three parts 10 11 12, lying above the member 9, so that the latter takes the downward pressure,

forcing the said center member and all the members downward, the leather will be forced hard against the jointless bottom and side walls of the female members and an impression of the engraving will be produced on the outer surfaces of the leather, the leather loop being given the proper loop shape, as will be obvious, and inasmuch as such joints as come upon the leather are open on the inside of the box there will be no joint im ressions on the exposed side of the box or oop, thus conducing to a more perfect ornamentation. The male die members having been brought to their final bearings in the member 6 to produce the desired impression, the free ends of the leather, which are preferably skived, are bent down into the aperture 8 on top of the male die members and joined 'together by tacking, cement, or otherwise. They are preferably held under pressure until the leather assumes the final shape, as shown in Fig. 5,- thus completing the loop, after which the male die members may be forced endwise through the end openings of the aperture 8 and are thus removed from the female die, and the box or loop is completed.

Having thus described the invention, what l I claim as new is- -The improved loop-die comprising a fe- IOO f Y Y Y l 325,9@9
